'Declaration
 
Public Shared Function LessThanOrEqual( _
   ByVal left As TdPeriodTime, _
   ByVal right As TdPeriodTime _
) As Boolean

'Usage
 
Dim left As TdPeriodTime
Dim right As TdPeriodTime
Dim value As Boolean
 
value = TdPeriodTime.LessThanOrEqual(left, right)

public static bool LessThanOrEqual( 
   TdPeriodTime left,
   TdPeriodTime right
)

public:
static bool LessThanOrEqual( 
   TdPeriodTime left,
   TdPeriodTime right
) 

Parameters

left

An instance of TdPeriodTime.

right

An instance of TdPeriodTime.

Return Value

In order to perform this comparison the beginning and ending bounds of the left and right operands are compared against each other. The left is equal to or less than the right if the following is true:

    ((left.Begin < right.Begin) OR (left.Begin == right.Begin AND left.End <= right.End))

The value returned is true if the left is less than or equal to the right, false otherwise.

Comparison operators always returns false if one of the operands is Null. Therefore, you must not assume that the reverse condition is true. For example you cannot assume that the left operand is greater than the right operand if the LessThanOrEqual operator returns false.
